Practice that nobody assigned.
Numeros is a game first. The practice is a side effect of trying to win it.
Three things, all at once.
Math facts, fast.
Addition, subtraction and times tables, pulled from memory under a little friendly pressure, over and over in a single game.
Order of operations.
PEMDAS stops being a rule on a poster. Get it wrong and somebody at the table will tell you.
Checking the work.
Players verify each other's grids. Catching someone else's mistake turns out to be the best part.
What a phone takes out of a day.
Of screens, every day
Average daily entertainment screen use for 8 to 12-year-olds in the U.S. Schoolwork not included.
Common Sense Media census, 2021Has a phone by age 8
One in four children has their own cellphone by the time they turn eight.
Common Sense Media census, 2025A day, age 8 and under
Daily screen time for the youngest kids. Four in ten have their own tablet by age two.
Common Sense Media census, 2025Kids in one U.S. study
Among 9 and 10-year-olds, more screen time went with lower grades, more behavior problems and worse sleep.

Studies reviewed
A 2023 research review pulled together 19 studies of number board games played with children aged 3 to 9.
Balladares et al., Early Years, 2023Of math tasks improved
After the game sessions, children's math skills improved significantly on more than half of the tasks measured.
Same reviewTwice a week
The average session in those studies, for about six weeks. That is roughly one game of Numeros.
Same reviewScreens involved
100 tiles, a bag and a table. Nothing to charge, download or log in to.
Those studies tested other number games, mostly with younger children, and the screen figures show a link, not proof of cause. Numeros itself has not been studied. We are telling you what it practices, not promising a result.
Works when the kids aren't the same age.
You don't need multiplication to play. A grid built entirely from addition and subtraction is a legal grid.
Younger players stick to + and −. Older ones reach for × and ÷ to burn through tiles faster. Everyone draws from the same bag, at the same time, in the same game.
At home
Clear the table and pour out the bag. A game runs 15 to 30 minutes, so it fits between dinner and bedtime. There is nothing to charge, download or log in to.
In a classroom
One bag seats a group of up to five. There is no prep beyond pouring out the tiles, and the rules are short enough to read aloud.
Starting younger
For the first game or two with a seven or eight-year-old, pull the × and ÷ tiles out of the bag and play with just + − and =. Add them back once building equations feels easy.
With mixed ages, give the younger players a two-tile head start, or pair an older kid with a younger one and let them play as a team.
The honest questions.
What ages is it for?
It's built for ages 7 to 12, and it works for anyone who can add and subtract. Adults play too, usually harder than they planned.
Does my kid need to know multiplication?
No. You can win with nothing but addition and subtraction. Multiplying and dividing just lets you use up tiles faster.
